3.       By an agreement dated 27th October 1992 (herein "the Water Purchase
         Agreement"), between the CUSTOMER and OCL, the Original Agreement was
         cancelled and replaced by the Water Purchase Agreement, which,
         inter-alia, extended the term of the water supply until 31st December
         1999, and expanded the capacity of the Plant to 850,000 US gallons per
